This is no based on proven facts. It is based on personal experience and preference
I have been gambling for the past 2 years on sports , specifically soccer and i find it more better than Revshares and HIYPs, It's not an easy thing to do but ,it's the same as trading on a volatile market. It's either you win big or lose big ,however in my case i have mastered eliminating house edge and increase my odds of winning therefore winning. Now with Bitcoin online bookies/Betting sites i can transfer a small amount of satoshis then choose the matches i'm betting on right after statistical analysis. Predicting a game of soccer is not easy ,but one can capitalize on factors affecting the overall outcome of the game.
Most Major soccer leagues will be opening Mid-August and wow , so much Bitcoin/money to be made...
I really like it to. I didn't do it on a regular basis, but after entering the Tipster Championship on this forum, I think I got more methodical in betting.
It was nice to see my progress being marked, and competing against others. I don't think I'm very good at it, and I find it very hard, so right now Im still just gaining experience by keep betting over the time. I'm having some profit which is of course great and keeps me going I guess.
Maybe if I continue to get profit in the long run, I will increase my betting bankroll and get more serious about it.
